Application filed April 1, 1902.

T (tZZ 1077/0777, it may concern.-

Be it known that 1, PAUL BLAUBACH, resid ing at Bremen, in the Empire ofGermany, have invented certain new and useful Improvements in Machineryfor Manufacturing Patterned Linoleum; and I do hereby declare thefollowing to be a full, clear, and'exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to'the accompanying drawings, whichform part'of this specification.

The present invention relates to a machine for manufacturing patternedlinoleum.

The essential feature of the invention consists in the molds by means ofwhich the colored composition is applied to the fabric, be.- ingarranged to travel through the machine and gradually be filled'with allthe colors of the pattern. Above the molds are located perforated platesor stencils capable of being 'moved up and down, each of which-presentsthe contour of the pattern corresponding to one color. These stencilsare raised for the purpose of allowing the molds to travel farther andafter the molds have taken up their pressing-block of which profilesaccording to the pattern and is provided with electromagnets, uniformlyor otherwise distributed. By means of the latter the mold-frame afterthe pressure has been imparted is raised from the fabric and by the aidof a suitable device conducted tothe front of the machine, where it isset upon the table as first mold ready for being again advanced. Thismotion is effected by means of a movable table of wood or metal, abovewhich the fabric for the composition, consisting of some lightmaterialsuch as canvas, nettle-web, &c.-is stretched. Afterward thisfabric is removed from the linoleum and the latter pressed upon a strongjute or like fabric. This permanent base or backing receives thelinoleum, through which the jute travels also.

The invention is illustrated by the appended drawings, which show oneconstruction of the machinery.

Figure 1 is an elevation of the machine' traveled to and fro.

Serial No. 100,988. (No model.)

Fig. 2 is a plan view, partly in section, illustrating the arrangementof the stencil-plates and block. Fig. 3 is a detail View drawn to alarger scale and showing a vertical section of half of the press-blockand cooperating parts. Located above the table 0 and moving with it isthe fabric employed to receive the composition and afterward removedwhen the length of linoleum is formed. The table 0 consists of anendless apron or traveling surface of slats, metal, or the like andpasses over the rollers 7) Z), for the regular motion of which a spindlem is provided, while it is stretched by a tension device a. Upon thisendless apron, and particularly upon the fabric lying on it, the, molds(Z, closely connected,- are placed and travel with the fabric. They formto a certain extent a continuous series of molds, each of which isadvanced in an endless course from the first position to the last andfrom here again to the first. Above the apron is located a frame E,carrying a plurality of stencils a, 0 e 0*, and 0 each of which isprovided with an opening or perforation adapted to permit material of acertain color to be applied to one part of the mold and to cover theremaining portion.

The openings in the succeeding stencils are so arranged that takencollectively they form the complete pattern. The frame E is raised andlowered by racks a, operated by gears m on a shaft m Above the table isarranged a traveler on rails g g,'whereby by means of hand-crank 74 orthe like a block it can be The pressfor example, a hand-pressZ 'isarranged below the block 7b, which can thus be depressed upon thecomposition. The press Z is of simple form, comprising simply a screw Z,having its upper end journaled in the block Zr. A handwheel Z has athreaded sleeve engaging the screw Z, and a swiv'eled frame Z on thelower side carries a plate X, in which are mounted a plurality ofelectromagnets m, which may be energized to cause the mold which hasbeen pressed to adhere to the press-frame and be lifted therewith.

The length of linoleum is produced in the following manner: Thecomposition, with the first color, is laid in the mold d through thestenoil 6, since the latter covers all those parts of i the pattern ofthemold which are not to receive this color. Hereupon the table-apron(mvith the fabric, is so far advanced that the first mold comes to restexactly under the second stencil and can receivethe second color. Afterbeing filled the apron is again advanced through the length of a mold.When then the mold has received all the colors, it comes below the pressZ, and the loosely-lying composition is firmly pressed to a compactmass. The mold which has thus been standing below the press is nowraised by the operation of the hand-wheel until it is clear of thestencils and the carriage 9 moved back along rails until the mold is ininitial position. The length of linoleum after being so pressed issubjected to the usual process and conducted to a press. Into the latteris fed the fabric which is to serve as permanent base or backing for thelinoleum and is pressed upon the composition, which on leaving the pressthe temporary backing of canvas or the like is removed. Beforecommencing to move the table and the backing the stencils are elevatedand on completion of motion again sunk upon the mold, for which purposeany suitable device may be employed. The molds may be convenientlyelevated by means of elect-romagnets :0, which efiect uniform ascent andprevent warping or fracture.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A machine for manufacturing patterned linoleum, comprising travelingmolds corresponding in number to the number of colors contained in thepattern, and stencils above said molds, so constructed, that the partsof the pattern of the mold which are not to receive the particular colorare covered over by the material of the stencil, substantially asdescribed.

2. A machine for manufacturing patterned linoleum, comprising a tablehaving a traveling motion molds advanced by said table corresponding innumber to the number of colors contained in the pattern, and stencilsabove said molds, so constructed that the parts of the pattern of themold which are not to receive the particular color are covered over bythe material of the stencil, substantially as described.

3. A machine for mamifacturing patterned linoleum, comprising atraveling table carrying the temporary base for the linoleumcomposition, molds advanced by said table corresponding in number to thenumber of colors contained in the pattern, stencils as specified abovesaid molds, and means for pressing the linoleum composition after theapplication of the whole of the colors constituting the pattern,substantially as described.

4:. A machine for manufacturing patterned linoleum, comprising atraveling table carrying the temporary base for the linoleumcomposition, molds advanced by said table corresponding in number to thenumber of colors contained in the pattern, stencils as specified abovesaid molds, means for raising and lowering said stencils, and means forpressing the linoleum composition after the application of the colorsconstituting the pattern, substantially as described.

5. A machine for manufacturing patterned linoleum, comprising atraveling table carrying the temporary base for the linoleumcomposition; molds advanced by said table corresponding in number to thenumber of colors contained in the pattern, stencils as specified abovesaid molds, means for raising and lowering said stencils, means forpressing the linoleum composition after the application of all thecolors, and means for returning the molds to their initial positionafter the pressing operation, substantially as described.

6. In a machine for manufacturing patterned linoleum by means of molds,a pressblock provided with electromagnets for the purpose of elevatingthe molds subsequent to the pressing operation, substantially as described.

In witness whereof I have hereunto signed my name, this 17th day ofMarch, 1902, in the presence of two subscribing witnesses.
